Definition
Biomanipulation of organisms to perform practical tasks for humans
Term
Genetic Engineering
Definition
Technology: Creates Recombinant Plasmid w/ restriction enzymes
Term
Conjugation
Definition
Transfer of DNA (donar to recipient) through a SEX PILLUS
Term
Transformation
Definition
Uptake of naked foreign DNA by host bacterium (no bridge or virus)
Term
Transduction
Definition
Transfer of foreign DNA by a VIRAL vector
Term
Griffith (1928)
Definition
Microbiologist; 1st to discover TRANSFORMATION (used mice)
Term
Recombinant DNA
Definition
DNA from two different organisms spliced together
Term
Plasmid
Definition
Extrachromosomal, circular piece of DNA in bacteria (survival)
Term
Plasmid Chimera
Definition
Name for PLASMID with foreign DNA spliced into it
Term
Restriction Enzyme (1971)
Definition
Bacterial enzyme prevents phage DNA from replacing (key to Genetic Engineering)
Term
Palindrome
Definition
Restriction site; complimentary BP's run in reverse (5-6 BP in length)
Term
Sticky Ends
Definition
Restriction enzymes cut in ways that leave exposed single strands
Term
DNA ligase
Definition
Enzyme that JOINS sticky ends by Complementary base pairing
Term
Genomic Library
Definition
Complete collection of cloned DNA fragments from an organism
Term
GMO
Definition
Genetically Modified Organism w/ new artificial genes (pest/herb resist)
Term
Transgenic
Definition
Organism (cow/pig) carrying specific genes from another species
Term
Agrobafctyerium tumefaciens
Definition
Plant bacterium; causes "tumors"; R-plasmid used to inject desired gene
Term
Antibiotic Resistance
Definition
Characteristic used to SELECT bacteria with recombinant plasmid
Term
Gene Cloning
Definition
Duplication of identical genes in bacteria (through PLASMID transfer)
Term
Animal Cloning
Definition
identical animal created from donar nuclei replacing host enucleated egg
Term
Engineered Vaccines
Definition
Viral genes CLONED in yeast cells -> mass produced viral antigens
Term
Vehicle
Definition
Sometimes called a VECTOR; carries foreign DNA into host
Term
Foreign DNA
Definition
Carries desired genes (called "passenger"); it replicates in HOST cell
Term
PCR
Definition
Polymerase Chain Reaction; mass produces small DNA pieces in test tube
Term
Gel Electrophoresis
Definition
Technique: Separates DNA fragments (RFLPs) by length (# BPs)
Term
Gene Therapy
Definition
Technique: Replaces "BAD" genes with "GOOD" genes
Term
DNA Fingerprinting
Definition
Technique: Develops bands from RFLPs; associated most with forensics
Term
Autoradiograph
Definition
Exposing Electrophoretic Markers to X-ray film -> banding pattern
Term
Nucleic Acid Probe
Definition
Complementary radioactively labeled DNA used to find desired gene
Term
E. coli
Definition
Primary bacterium used in Genetic Engineering
Term
Antibiotic Resistance
Definition
Characteristic commonly used to assess uptake of R-plasmid with desired gene
